Abstract
A keyboard may be generally illuminated while also providing for key-specific illumination of one or more particular keys. The keyboard may be generally illuminated using any configuration of any number of suitable illumination sources. The keyboard may selectively illuminate any key or keys together with or apart from the general illumination of other keys. The keyboard may also variably illuminate certain keys to aid the user in navigating the keyboard.
